in CCNA & CCENT
On books the frame is said to have 46 to 1500 bytes data field. But I can't seem to find info of the maximum size of a segment or packet. Both lammle book and odom book don't show it. Even wikipedia.

because it is not a fixed number. Data can have various sizes depending on the type of data inside the frame.

Yeah it depends on what you're sending. If the data is tiny and below 64 bytes I believe the packet will be "padded" out to take it up to this size -

Let's say I'm copying a 500MB exe file on the LAN? Isn't it that the transport layer segments the data from the upper layers? So what's the maximum size of a segment?

Wouldn't it also depend on what the specific application will allow to send? -

The source host accepts from the transport layer a segment of maximum size 1,000 bytes and a destination host address.
